Abstract

Background: The advantages of the I-gel supraglottic airway device include ease and speed of insertion, reducedtrauma incidence, an integral bite block, gastric access, a non-inflatable cuff and superior seal pressure. The primarygoal of this study was to compare airway leak pressures and the fibreoptic view in the supine and lateral positions.Our secondary aim was to analyse the effects of I-gel insertion on haemodynamic parameters.

Methods: One hundred patients undergoing saturation biopsy due to prostatic hyperplasia were recruited to this prospectiverandomised study. An I-gel device was inserted in the supine position. Taking of measurements, patients wereplaced in the lateral decubitus position. Mean arterial pressure, heart rate, peripheral O2 saturation and end-tidal CO2were recorded before and after insertion. We recorded the number of attempts and insertion time for the I-gel device.Oropharyngeal leak pressures and I-gel device positioning were scored in the lateral decubitus and supine positions.

Results: It was possible to insert the I-gel device in 88 patients on the first attempt. The median time for insertionwas 7.97 ± 2.18 sec. The mean arterial pressure and heart rate decreased 1 and 2 min after insertion. Oropharyngealleak pressure was similar in the supine (27.45 ± 5.37 mm Hg) and lateral decubitus positions (26.04 ± 4.92 mm Hg)(P > 0.05). On fibreoptic examination through the I-gel device, the scores of patients were comparable in differentpositions (P = 0.542).

Conclusion: As there was no significant difference in oropharyngeal leak pressure and fibreoptic view, we concludedthat the I-gel device may be used safely in both the supine and lateral positions.
